Tender specification
EC centrifugal fans – RadiPac
sizes 280 to 630
Direct-drive, single inlet centrifugal fans with backwards-curved high-performance centrifugal impellers
made of composite material, based on a GreenTech EC external rotor motor with integrated control
electronics.
One-piece impeller made of high-strength, glass-fiber reinforced composite material. 5 backward-curved andtwisted 3D blades optimized in terms of strength. Blade inlet with rounded flow contour and profile tapered toward
the rear to the blade outlet. Corrugated cover plate for optimum filling level. Flow-optimized inlet ring made ofcomposite material with pressure test nipple.
Motor-impeller in accordance with DIN ISO 21940, statically and dynamically balanced on two planes to balancing
grade G 6.3.
GreenTech EC external rotor motors achieve or exceed the efficiency specifications in accordance with efficiency
class IE5 (IEC TS 60034-30-2:2016), magnets without the use of rare earths, maintenance-free ball bearings withlong-term lubrication, theoretical nominal service life of at least 40,000 operating hours.
Soft start, integrated current limitation, automatic resonance detection (from an input power of 2kW), extended
voltage input 1~200-277 V, 50/60 or 3~380-480 V, 50/60 Hz. The fan can be used with all standard power supply
networks with unaltered air performance. Integrated control electronics, low-noise commutation logic; 100%speed control; all fans have an RS485/MODBUS RTU interface, no shielded cables are required for the power
supply. All 1~ types feature integrated active PFC (Power Factor Correction) to reduce disturbing harmoniccontent. Terminal box made of aluminum/plastic with easily accessible connection area, environment-resistantcable glands.
Version for wall mounting:
Ready-to-install support bracket version intended for wall mounting (size 280 to 630). Support structure made ofbent round steel or steel pipe, welded and coated in black. Mounting plate made of Sendzimir galvanized sheetsteel.
Ready-to-install module version intended for wall mounting (size 310 to 630). Support structure made of bent
round steel or steel pipe, welded and coated in black. Air guide module mounted on the pressure side, made offour aerodynamically shaped, Sendzimir galvanized sheet steel segments.
Inlet ring made of composite material with pressure test nipple. Installation position with horizontal motor shaft
and vertical motor shaft with rotor on bottom. Vertical installation position with rotor on top on request.
Any work required for isolation from structure-borne noise is to be performed by the customer.
The fan satisfies the applicable EMC guidelines and requirements with regard to harmonic effects (see applicabledata sheet for specific figures).
Documentation and marking in accordance with the applicable EU directives.
Reliable performance data, air performance measurements taken on an intake-side chamber test rig inaccordance with ISO 5801 and DIN 24163. Noise measurements taken in an anechoic room in accordance withDIN EN ISO 3745.
